Hmm, true, this makes it a bit more complicated.
If you submit it then to stable and the maintainers should definitively should
add the context for why a 1:1 cherry-pick is not an option, like it being rather
huge and the fixing the misalignment as side effect of correcting the tracking
of subreq->transferred where sensible before calling into the new
netfs_read_subreq_terminated helper that replaced the netfs_subreq_terminated
one you're adapting here, at least FWICT.

So FWIW, while I also would prefer some comment from upstream, I'm also fine
with applying this now, as it seems reasonable workaround and letting the kernel
through to the test repo to allow those affected to test it would also to get us
some more QA out of this patch before moving it to more stable repos.
